SOLID-RUBBER VEHICLE-TIRE.

SPECIFICATION forming part of Letters Patent N o. 674,478, dated May 21, 1901.

Application le October 6, 1900. Serial No. 32,288. (No model.)

T0 all whom it may concern,.-

Be it known that I, FRANK A. SEIBERLING, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful Improvement in Solid-Rubber Vehicle- Tires, of which the following is a specification.

My invention has relation to improvements in that class of vehicle-tires in which the wood felly is surrounded by a metal tire on which is secured an outside tire of flexible vulcanized rubber having embedded longitudinal wires to bind the rubber against escape, and is an improvement on the device for which I made an application for Letters Patent of the United States on September 2l, 1900, Serial No. 30,925.

The Object of my invention is to provide additional means for securing the rubber tire in place and especially to prevent buckling between the cross-bolts that bind the side annular plates together.

To the aforesaid object my invention consists in the peculiar and novel construction ,arrangement, and combination of parts hereinafter described and then speciically pointed out in the claims, reference being had to the accompanying drawings, forming a part of this specification. n

In the accompanying drawings, in. which similar reference-numerals indicate like parts in the different views, Figure l is a section of the rubber-tire wires, metal tire, side plates, and wood felly, showing one of the retaining-bolts, and at the linea a: of Fig. 3; Fig. 2, asection of the same between the retaining-bolts at the line Z Z of Fig. 3 to show the supplemental securing-wires; and Fig. 3, a side elevation of a portion of the felly, side plate, and rubber tire partially broken away to show the arrangement of the wires.

Referring to the figures, l is the wood felly, and 2 the metallic tire, which is a plain endless band, on which is the solid-rubber tire 3 of practically the ordinary type in crosssection with a fiat base and substantially straight sides fora distance thence sloping inward and curved at the top or tread portion. This rubber portion is made and vulcanized annular or endless, with two endless parallel wires 4 embedded and vulcanized therein. As in the case hereiubefore referred to this rubber portion is made of such internal size as will require a slight pressure to 55 force it from one side onto the iron tire, where it will press with considerable tension force.

When the rubber portion has been placed on the metal tire, annular plates 5, with the outer periphery curved outward and of sufli- 6o cient width to cover the outer portion of the felly, the iron tire, and .thesubstantially iiat portion of the rubber, and to extend slightly above the corner where the sloping part commences, are placed on opposite sides of the Wheel and secured to the felly by bolts 6, passing through at intervals about the4 wheel. Similar bolts 7 pass through the plates 5 and rubber tire 3, and preferably touching the wires 4, and so placed as to be intermediate 7o of the bolts 6.

As thus far described this device does not differ essentially from the case hereinbefore referred to. The additional and novel feature is as follows: Inclosed in the rubber tire at intervals, in substantially the circumferential line of the bolts 7 and intermediate thereof and vulcanized in the rubber, are a number of short cross wires or rods 8, slightly less in length than the width of the rubber 8o tire to permit the compression of the latter, and these wires are arranged to bear against the wires 4. These wires 8, while not materially adding to the weight of the tire, will by holding against the wires 4 prevent the swell- 85 ing or buckling of the rubber tire between the bolts 7.

I claim as my invention- 1. An improved tire consisting of an annularly-constructed rubber band having in 9o section a iiat base and a rounded tread portion, and inelosing endless longitudinal parallelfwires and cross-wires arranged to engage the inner periphery of said parallel Wires, said longitudinal and cross wires being wholly 9 5 embedded within said tire, substantially as shown and described.

2. An improved tire consisting of an annularly-constructed rubber band having in section a flat base and a rounded tread porrou tion, with endless longitudinal parallel wires, and cross-wires less in length than the width of said tire arranged to engage the inner periphery of said'parallel wires, said longitudil and adapted to engage and press against the nal and cross Wires being Wholly embedded in said tire and vulcanized therein, substantially as shown and described.

3. The combination in a Wheel, of a felly, a metallic tire, an endless rubber tire surrounding and resting on the metal tire, having parallel endless longitudinal Wires, and a series of cross-Wires arranged at intervals inner periphery of the endless Wires, said 1ongitudinal and cross Wires being vvholl57 ernbedded and vulcanized therein, substantially as shown and described.

4C. 'The combination in a Wheel, of a felly, a metallic tire, an endless rubber tire surrounding and resting on the metal tire, and having endless Wires embedded therein, with oppositely-disposed annular plates arranged to cover adjacent parts of the felly and rubber tire, and two series of bolts, one whereof passes through the plates and felly at inter-
